Prohibiting paywall bypass software violates the principle that the client dictates how web pages are rendered, or requires carving out a special exception just for the publishing industry.

Viewed under a magnifying glass, it seems like a good thing to ensure the publishing industry can use soft paywalls, but taking a broader view, I think that breaks the web. I don't think soft paywalls are worth breaking the web, and even more broadly, governments should only regulate what users can do with data willingly sent to their computers in very exceptional circumstances.
